The two-dimensional code information structure mentioned below refers to the new two-dimensional code information structure proposed in the present application.
Fig. 1 is a schematic diagram of an overall architecture related to the solution of the present specification in a practical application scenario. In the overall architecture, three parts are mainly involved: the system comprises a two-dimensional code generating end, a two-dimensional code scanning and analyzing end and a server end. The two-dimension code generating end generates and displays the two-dimension code according to the two-dimension code information structure; the two-dimension code scanning and analyzing end scans the two-dimension code, analyzes the two-dimension code according to the information structure of the two-dimension code, and then executes corresponding business according to the analysis result; the server typically participates in order to facilitate the business.
The two-dimensional code generating end comprises a user terminal such as a mobile phone and a smart watch, the two-dimensional code scanning and analyzing end comprises a Point Of Sale (POS) machine, a cash register, a code scanner at an entrance Of a bus and other merchant terminals, and the service end comprises a server Of an e-commerce and a payment platform, or a server Of a bus platform. Of course, the merchant terminal generates the two-dimensional code in reverse, and the user terminal may scan and analyze the two-dimensional code, for convenience of description, this mode is referred to as a user main scanning mode, and the former mode is referred to as a user scanned mode.
The architecture in fig. 1 is exemplary, and not exclusive. For example, the architecture may not include a server, and after the two-dimensional code is generated, all related services are processed locally at the two-dimensional code scanning and analyzing end, and so on.
The following describes the embodiments of the present specification in detail.
Fig. 2 is a schematic flow chart of a two-dimensional code generation method provided in an embodiment of the present specification. The process in fig. 2 comprises the following steps:
s202: original content is obtained.
In the embodiment of the present specification, the original content includes data required to be used for executing a corresponding service in a current service scenario. Such as web address, account number, order number, preference code, business card, etc.
S204: generating a two-dimensional code corresponding to the original content according to a two-dimensional code information structure and the original content; the two-dimensional code information structure at least comprises an indication field and a data field, wherein the indication field is used for indicating one or more data elements in the data field which are needed to be used in a specified service scene.
In the embodiment of the present specification, in the generated two-dimensional code, the corresponding data element includes original content, and the corresponding data element can be extracted by scanning and analyzing the two-dimensional code, and is further used for executing a service.
In the embodiments of the present specification, specific contents of the indication field and the data field may be flexibly and conveniently defined according to actual needs.
For any single scene, when the scene changes, the specific contents of the indication field and the data field can be adjusted, so that the two-dimensional code can effectively adapt to the scene change.
The indication domain can indicate corresponding data elements in the data domain respectively for a plurality of service scenes simultaneously, so that the generated two-dimensional code can be simultaneously applied to the plurality of service scenes, namely, one-code multi-scene use.
In the embodiments of the present specification, the indication of the indication field to the data element may be one or more. The following four are listed as examples.
First, the presence of a data element in the data field is indicated. The data field generally has a plurality of data elements, and the data elements may be different in different service scenarios. Through the indication field, the data elements needed to be used can be configured in the data field according to the current service scene.
Second, a business definition of the data element is indicated. For example, for a traffic card service scenario, a certain data element is indicated to represent certain preferential information (such as student discount, accumulated amount discount, etc.), and a certain data element is indicated to represent a certain type of traffic card (such as student card, old card, etc., such as bus card, train month card, etc.).
Third, the location of the data element in the data field is indicated. E.g., 1 st, 3 rd, 6 th data element, etc., in the data field, thereby facilitating fast indexing of the required data elements.
And fourthly, indicating the matching relation between the service scene and the data element. And determining the data elements required to be used in the data domain according to the matching relationship and the current service scene.
In the embodiments of the present specification, in addition to the indication domain and the data domain, one or more domains may be included, such as one or more of the following: the code header field is used for identifying a maker of the two-dimensional code information structure; the code version field is used for identifying the version of the two-dimensional code information structure; and the verification domain is used for verifying the content of the domain contained in the two-dimensional code information structure.
By the method of fig. 2, the indication field and the data field can be flexibly and conveniently adjusted according to different service scenarios, so that two-dimensional codes suitable for one or more different service scenarios can be generated.
Based on the method of fig. 2, the embodiments of the present specification also provide some specific embodiments of the method, and further provide the following description.
In the embodiments of the present specification, there are various implementations of the indication field, for example, the indication field is implemented based on a structure such as a bitmap, or an array, or a linked list.
The following embodiments are mainly described by taking the example that the indication field is implemented based on a bitmap. In this case, the indication field may include a bitmap field composed of one or more bits having a correspondence with data elements in the data field, the bits being used to indicate their corresponding data elements.
For the convenience of understanding, the bitmap is described herein, and refers to a data structure representing a dense set (dense set) in a finite field, each element appears at least once, and no other data is associated with the element, which is widely applied in the aspects of indexing, data compression and the like.
The bitmap may particularly refer to a bitmap in standard ISO 8583, for example. In ISO 8583, a bitmap is a field or subfield within a message that indicates whether there are other data elements or data element subfields elsewhere in the message. A field is considered to be present only when the corresponding bit in the bitmap is set. For example, assume that a bitmap is a byte with a value of 0x82 (130 decimal), represented in binary as "10000010", correspondingly indicating that fields 1 and 7 are present in the message and fields 2, 3, 4, 5, 6, and 8 are not present.
Specifically, in the bitmap field proposed in the present application, for example, when a value of a bit in the bitmap field is a first value, it indicates that a data element corresponding to the bit exists in the data field; when the bit in the bitmap field takes a second value different from the first value, it indicates that the data element corresponding to the bit does not exist in the data field. If the first value is 1, the second value is 0; if the first value is 0, the second value is 1.
More intuitively, the embodiment of the specification also provides an example of a two-dimensional code information structure. The following description will be made with reference to tables 1 to 3. An example of the two-dimensional code information structure is shown in table 1 below.
TABLE 1
| Code header field | Code version field | Bitmap field | Data field | Check field |
The bitmap fields and data fields in table 1 are further illustrated.
Each bit in the bitmap field may correspond to a specific data element, and whether each bit in the bitmap field is set to 0 or 1 determines which specific data elements are present in the bitmap field. For example, assume that the bitmap field is 4 bytes long and contains 4 × 8-32 bits, as shown in table 2 below.
TABLE 2
| Bits 1-8 | Bits 9-16 | Bits 17-24 | Bits 25-32 |
| 10100110 | 00000001 | 10000000 | 00000001 |
The bitmap field and data field in table 1 are further illustrated.
The definitions of tables 1 and 2 indicate that in the data field, the 1 st, 3 rd, 6 th, 7 th, 16 th, 17 th, 32 th data elements exist, while none of the other data elements exist.
The data field contains specific data elements, and the data elements corresponding to each bit in the bitmap field may have explicit service definitions. Each data element is, for example, a Length-data element value structure, which is referred to as a Length-value (lv) structure. The data fields corresponding to table 2 are shown in table 3.
TABLE 3
In view of reducing the redundancy of data as much as possible, if the length of a certain data element is already clear, the value of the certain data element may be reserved in the data field. In addition, the data elements can reserve a custom field, and the custom field can contain nested sub-data elements, so that the expansion of the service can be facilitated.
Of course, the definitions in tables 1 to 3 are exemplary and not the only embodiments of the present application.
Based on the same idea, the embodiment of the present specification further provides a two-dimensional code processing method, which is explained from the perspective of a two-dimensional code generation end. Fig. 3 is a schematic flow chart of the two-dimensional code processing method. The flow in fig. 3 includes the following steps:
s302: and scanning the two-dimensional code and converting to obtain the character string represented by the two-dimensional code.
In this embodiment of the present specification, the character string is generated according to the information structure and the original content of the two-dimensional code, and the character string is encoded into a graphic form according to the encoding rule specified by the two-dimensional code, that is, the two-dimensional code is obtained, and step S302 is a decoding process corresponding to the encoding process.
S304: analyzing the character string according to a two-dimension code information structure based on the two-dimension code to obtain one or more data elements required to be used in the current service scene; the two-dimensional code information structure at least comprises an indication field and a data field, wherein the indication field is used for indicating one or more data elements in the data field which are needed to be used in a specified service scene.
S306: and executing the service under the current service scene according to the obtained data elements.
As can be seen from the above description of the embodiments, based on the two-dimensional code information structure, it is helpful to perform two-dimensional code related services effectively.
From the perspective of information coding bearing, the two-dimensional code information structure has very strong flexibility and expandability, can very conveniently support service upgrading or industry expansion, even support multiple scenes in one code, take service upgrading as an example, for example, in traffic card application, new preferential information or new traffic card types are added, only corresponding data elements or even one value definition needs to be added, and large data structure change cannot be involved.
From the perspective of the code scanning terminal, no matter what service is supported by the extension, the code scanning terminal is uniform in logic of data analysis, so that the condition that the terminal program needs to be modified for upgrading the service can be avoided, and the cost of terminal reconstruction is reduced.
In the embodiment of the present specification, it has been mentioned above that no matter two-dimensional code generation or two-dimensional code processing, an action of a server may also be involved, and for convenience of understanding, in a practical application scenario of a two-dimensional code provided in the embodiment of the present specification, a service flow of a scanned user mode and a main scanned user mode is provided, and fig. 4 and fig. 5 are service flow diagrams of the two modes, respectively.
The service flow in fig. 4 mainly includes the following steps:
the user mobile phone generates and displays the two-dimension code according to the two-dimension code information structure provided by the application;
the scanner of the merchant terminal scans the two-dimensional code to obtain an image, identifies the image, converts the image into a character string and then sends the character string to a processor of the merchant terminal;
the processor analyzes the character string according to the two-dimensional code information structure to obtain corresponding data elements;
the processor may send the data elements obtained from the two-dimensional code to the server for service processing according to specific needs, or may locally perform service processing; in the former case, after the server finishes processing, the server may send a corresponding service notification to the user's mobile phone.
The business process in fig. 5 mainly includes the following steps:
the POS machine generates a two-dimensional code according to the two-dimensional code information structure provided by the application, or acquires the two-dimensional code from a server; displaying the two-dimension code;
scanning the two-dimensional code by the mobile phone of the user to obtain an image, identifying and converting the image into a character string, and analyzing the character string according to the information structure of the two-dimensional code to obtain corresponding data elements;

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the embodiments of the apparatus, the device, and the nonvolatile computer storage medium, since they are substantially similar to the embodiments of the method, the description is simple, and for the relevant points, reference may be made to the partial description of the embodiments of the method.
The apparatus, the device, the nonvolatile computer storage medium, and the method provided in the embodiments of the present specification correspond to each other, and therefore, the apparatus, the device, and the nonvolatile computer storage medium also have advantageous technical effects similar to those of the corresponding method.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the various elements may be implemented in the same one or more software and/or hardware implementations of the present description.
As will be appreciated by one skilled in the art, the present specification embodiments may be provided as a method, system, or computer program product. Accordingly, embodiments of the present description may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, embodiments of the present description may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and so forth) having computer-usable program code embodied therein.
The description has been presented with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the description. It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.
The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.
Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
This description may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The specification may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
